Bulbasaur's one of my favourite. I have a venusaur and enough bulbasuar candies to create another one. Waiting for the right time to pop a lucky egg.

I am also collecting magikarps. Need 100 of them (400 candies to evolve)

You just need to put your pokemon in the gym when the counter is down to 0 to collect the coins, dont need to hold it for long. If not greedy 10 coins per day. Sometimes, you can just walk pass and slot one in when it changes hands.
